bug#22300: 25.1.50; Dired -- renaming folders/files to CamelCase/UPPERCASE/lowercase.

[Keith David Bershatsky]

I agree that `rename-file` could use a fix.

Once `rename-file` is ironed out on the C-source code level, I believe the tail 
end of `dired-do-create-files` will also need to be fixed because the 
`name-constructor`

(function (lambda (from) (expand-file-name (file-name-nondirectory from) 
target)))

returns the wrong path when used by dired-create-files.  
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22300#29

So, I believe it will be both areas of Emacs that need some TLC.
